` My `invention relates toV improvementsV in floose leaf binders and hasforI` its object the provision of an improved construction of thischaracter which is strong and feiicient in use and capable of economlcalmanufac- Other objects will appear hereinafter.

The invention consists in the combinations and arrangementsof partshereinafter de- .v

The form of construction illustrated in Figs. 1 to 5/inclusive comprisestwo cover members `12 and 13 detachably secured or bound together inbook form.- To effect such binding, each cover member is .provided ad-`jacent its bound edge with projectinglstrlps `14E and 15 projectingtoward the other cover member and cooperating with each other. Each ofsaid strips Vconstitutes one leg of a corresponding angle iron. theother leg of Y which is suitably embedded and secured in thecorresponding cover member as shown. The angle iron'leg 14 is providedat its ends with notches'l andthe corresponding cover member 12 isprovided with two bowed-leaf` binding springs l17 as shown. The otherstrip for cover member 15 is provided at its ends with back-turned guardmembers 18 and 19 `arranged as shown to providea space `for the guard19.V The latch spring .2l is. secured in reception .of the correspondingendsfofxtheVA strip V14C. Af pin 20 traverses thespace enclosed by theguard 18 and a` latch spring 21 Vis provided-tof cooperate withtheopposite place by means of a rivet22and is ,providedh with alip ortang'23 projectingthrough av .corresponding opening in Vthefstrip 15 andarranged `automatically tol engage the corre- Vsponding notches 16whenstrip 14 is inserted.4

The latch spring 21 is also `provided with-x..` an inwardlyturnedlip24engaging-.around thev end"` 19,"` said lip 24 striking;the-:end 19 whensaid latch` springlis pressed-,back suiiic'ientlyto releasethe latclrlip23 fromnotch 16 thus preventingfurther movement of said a latch` springand consequent injury'thereto. j

By this arrangementit will be noted tha-ta plurality of loose leaves 25may-be readily assembled or arranged` on. the 1 cover member lwiththeiredgesresting :against thetcorrespondingY strip 15. z :ITO bind `theleaves 25 f inplaceall that is necessaryis to insert and engagethelnotch lat the corres ondingend 1 of the strip letwith the pin 2O anthen swing the other end .of the strip 14 ldownwardly un, tilthe notch16 in the other end automatically engages the latch lip 1235n thus`locking lthe "jstripsfincooperating relatioiiwith each other. `Thisactioncausessprngs .17.10, rest.upon n i and bind the looseleaves25 inplace. When-.V

it isdesired tofrelease leavesz25', alln thatjis f 24: to release thelatch y23 from thecorrespondl `y`ingr notch 16 whereupon fthe spring1t-.will

separate the covernie1nbers,thus permitting of ready removalof-said`leaves.- Y The modification illustrated in Figs. 6ft 11inclusive providesfor suicient adjustment to accommodate a wide rangeinthe number of leaves 25 which may be bound.` To this end, one ofthestrips 14 i is provided with a plurality of notches 16 in its ends andthe corresponding cover members Vare provided with a doublebowedleafspring 17 as shown.

Inecessaryfistfo lpress outwardly uponlip The other strip 15l is madealso of a height Y corresponding with the strip 14: and isprovided withcorresponding back turned guide guardsY 18 andj19 to receive the endsvof the strip 142.V In this. 'casetwo of the latch springs 21 areprovided, one atpeach end.

Otherwise the construction is the same as that already described. 1 Bythis arrangement it will be noted that piles of loose lea-ves 25 .ofvarious'depths maybe placed upon .cover member 13 and readilyfbound inplacek by inserting the strip 14 in the space behind the guide guards 18and 19 and pressing downwardly thereon. This will cause the latch spring23 to engage automatically with the notches 16 and loch the cover 12 inbinding position to hold said leaves securely, the different notches 16permitting of a wide range of adjustment to accommodate differ entnumbers of leaves 25, as will be readily understood. When it is desiredto release the leaves, all that is necessary is to press outwardly onone or the other of the lips 24 whereupon the spring 17 will force thecover member l2 upwardly when the latch 23 is raised from thecorresponding notch 16.

YVhile I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification without departing from the spirit of theinvention. I, therefore, do not wish to be limited to the precisedetails of construction set forth, but desire to avail myself of suchvariations and modifications as come within the scope of the appendedclaims.

Having described my invention what I claim as new, and desire to secureby Letters Patent is:

1. A binder comprising two cover members bound together in book form,each cover member being provided at its bound edge with a stripprojecting therefrom toward the other cover member, the ends of one ofsaid strips being bent back to form guide guards; a spring latch memberon one end of said last mentioned strip cooperating with thecorresponding guard, there being means on the other strip to detachablyengage said latch; a detachable engagement between the other ends ofsaid strips; and a leaf spring on one cover member and arranged to restupon and bind leaves between said cover members, substantially asdescribed.

2. A binder comprising two book cover members, each cover member beingprovided at one of its edges with an angle iron having one leg securedin the body of the cover, the

other leg projecting therefrom to form a sccuring strip; one of` saidstrips provided with back-turned ends forming guide guards, meansassociated with said `guidey guards and cooperating means associatedwith the ends of said other strip for detaehably securing said stripstogether to form a book with said cover members; and a leaf spring onone cover member and arranged to rest upon and bind leaves between saidcover members, substantially as described.

A binder comprising two book cover members, each cover member beingjn'ovided at its bound edge with a strip jnojccting therefrom at anangle; one of said strips provided with back-turned ends forming guideguards; means associated with said guide guards and coope ating meansassociated with the ends of said other strip for detachably andadjustably securing said strips together; and a leaf spring on one covermember and arranged to rest upon and bind leaves between said covermembers, substantially as described.

4. A binder comprising two cover inembers bound together in book form,each cover member being provided at its bound edge with a stripprojecting therefrom toward the other cover member; one of said stripsbeing provided with back-turned ends formingr guide guards and the otherstrip being provided in its ends with corresponding notches; springlatches cooperating with said guards and provided with means engagingsaid notches; and a. leaf spring on one cover inember and arranged torest upon and bind leaves between said cover members, substantially asdescribed.

In testimony whereof I have signed my name to this specification. i
